Abstract: ABSTRACT       A turbocharger system.  One impeller of the turbocharger is driven by exhaust gas from an internal combustion engine, the other impeller functions as a pump to either compress air or to pump air in order to convey granular material.  The impeller wheels are spac-ed and are mounted at the ends of a common shaft.  The shaft is continuously lubricated, the spent lubricant being fed to an oil sump (crankcase).  The specific improvement is a pressure bleed passageway between the chamber which receives engine exhaust pressure and the oil exhaust line.  The bleed allows a portion of engine exhaust to pass to the sump exhaust line and assist oil flow to the sump by virtue of a pressure differential.  This action, in turn, inhibits spent oil from passing through the seals and passing into either or both impellers when oil sump (crankcase) pressure is higher than atmospheric or where there are unfavor-able to gravity flow conditions existing in the oil return line.  Another portion of the system bleeds air from a high pressure reservoir to the interior of the oil sump line to assist spent oil flow to the sump.

Abstract: ABSTRACT OF THE DISCLOSURE An electronically operable multiple-choice response evaluating apparatus. The apparatus comprises a relatively small and portable housing having a plurality of first input switches which are manually actuable by a user in order to introduce a code of indicia, as for example, a multiple-element alpha-numeric indicia, representative of a question. The housing also includes a plurality of second input switches which may be manually actuated by the user in order to introduce an indicia representative of a selected one of a plurality of possible answers for a question. The housing also includes electronic processing means, such as a microprocessor, which compares the code of indicia representative of the question with the indicia representative of the selected answer and makes an evaluation such as determining whether or not the user of the apparatus selected the one proper answer for that question. The apparatus may include one or more sheets having the questions listed thereon and with the identifying code of indicia for each question. In like manner, two or more answers may be provided on the sheet with each question, and again each answer will have indicia representing that particular answer. Thus, the user of the apparatus selects a question, uses the first input switches to introduce the code for that question, then selects the proper answer and uses the second input switch to introduce the indicia for that answer. A response mechanism, such as a pair of lights on the housing, will indicate whether or not the user selected the right answer. It is not necessary to have any physical interraction between the sheet and the housing in order to introduce answers and questions or to render a -1-determination that a correct answer has been selected. The code representative of the questions and the indicia representative of the answers are processed through an algorithm programmed into the processing means so that the relationship between the code of indicia for the question and the indicia for the answer are undiscernible to the user. Moreover, the memory capacity in the microprocessor can be relatively small since the same fixed mathematical procedure of comparing answer indicia with questions codes occurs for each question and all answers for each question.

Abstract: Abstract of the Disclosure Method and apparatus are disclosed for controlling the relative humidity of a soil environment at a pre-set value using an enclosed volume of a water-soluble or water-swellable material, said enclosed volume separated from the external environment by a relatively stiff and strong semipermeable membrane and separated from a pressurized irrigation water supply by a water-impermeable constrictable flexible section or diaphragm in the supply line.  When the soil is more moist than the pre-set value, intake of water through the membrane causes expansion of the water-swellable material which in turn constricts the flexible section of the water supply line to interrupt the flow of water to the soil.  When the soil moisture falls below the pre-set value, egress of water from the water-swellable material releases the constricting force on the flexible section  thereby allowing increased flow of water through the flexible section of supply line to the soil.           This process, which is called hygrostatic irrigation, is especially useful for optimized and unattended control and delivery of water to the root system of a plane growing in soil, particularly a potted plant, as well as for water con-servation in the agricultural irrigation of arid regions.  It also permits the optimized delivery to a plant, on a continuous basis in proportion to the water consumed, of nutrients, e.g. fertilizers dissolved at appropriate low concentrations in the supply water.

Abstract: VACUUM INTERRUPTER LATCH RELEASE MECHANISM            Abstract of the Disclosure A vacuum interrupter latch release mechanism employs a pivotably mounted trigger action arm in cooperation with a support arm assembly to resist the force of a main spring until the normally closed interrupter must be opened.          Rotating the trigger action arm causes a catch on the trig-ger arm to become disengaged from an associated stop pro-vided on the support arm assembly and allows the support arm assembly to pivot under the force of the main spring while being resisted by its weaker support spring.  The rotation of the support arm is accelerated by the main spring.  After a short stroke, an associated linkage impacts a stop on the vacuum interrupter which then becomes opened.  The large force of the main spring causes virtually no wearing effect on the catch and stop faces over long periods of continuous operation.

Abstract: Abstract of the Disclosure A magnetic compass has been devised which is of the type having a pivot point displaced above the plane of the permanent magnets so that the distance of displacement of the pivot point with respect to the center of force will reduce the tilt angle or tipping otherwise caused by changes in latitude when the compass is to be operated in different parts of the world and a spherical needle bearing can be employed at the pivot point as a result of the increased pendular effect achieved by displacing the pivot point above the magnets.  The need for a lift assembly to cushion the pivot point is eliminated while providing for an extremely rugged and versatile magnetic compass which will serve as a light, portable pocket transit capable of measuring hori-zontal and vertical angles as well as being used as a pris-matic compass, level, clinometer, plumb or alidade.

Abstract: SELF ALIGNING PAPER FEED ROLLER ASSEMBLY                   Abstract A paper feed roll assembly is disclosed which is pivotally mounted on a central point with three degrees of freedom of movement.  The feed rolls are engageable with the periphery of the platen. Additionally, the support for the paper feed rolls is deflectable about the central point by a feed roll release member to effect the withdrawal of the feed rolls from the periphery of the platen to enhance paper insertion and removal.  The pivot point support provides for freedom of movement in the three necessary degrees of freedom to allow equilization of feed roll force against the platen and for alignment of the feed rolls with the periphery of the platen to insure proper paper feed.  The feed roll truck frame, by virtue of its pivotal mounting, may be deflected downward to permit release or insertion of the paper.  A deflection means or eccentric bar is disclosed for deflecting the truck member away from the periphery of the platen against the force of the pivot support acting toward the platen.

Abstract: COAL GASIFICATION AND PRODUCTION    OF BY-PRODUCT SUPERHEATED STEAM      (D#76,476-1-F) ABSTRACT       Coal or other high ash containing carbonaceous solid fuel is reacted with a free-oxygen containing gas, with or without a temperature moderator, in a down-flow partial oxidation gas generator to produce a stream of raw synthesis gas, fuel gas, or reducing gas.  A large portion of the combustion residue, i.e. molten slag and/or particulate solids that is entrained in the down-flowing generated gas stream is removed by gravity when the gas stream is passed through a diversion chamber.  The separated solid material and molten slag pass down through an outlet in the bottom of the diversion chamber and into a pool of quench water below. Preferably, a small portion of the hot gas stream to pre-vent plugging.  The main gas stream leaving the diversion chamber through the side outlet passes upward through a solids separation zone, optionally including gas-gas quench cooling, cyclones, filters, impingement separators, or combinations thereof.  Next, most of the sensible heat in the gas stream is recovered by indirect heat exchange with boiler feed water and steam.  Saturated and superheated steam are produced.  In the main gas cooling zone, the hot gas stream with a substantially reduced solids content is passed serially through the tubes of two or more communi-cating shell-and-straight fire tube gas coolers.  Saturated steam, which is produced in one, or more of said gas cool-ers, is superheated in another of said gas coolers.  Each gas cooler may have one or more passes on the shell and tube sides and is preferably in an upright position with fixed tube sheets.
